These batteries claim to have a very long shelf life but have them less than a year and half the unused package were dead. I brought them back to Sam's Club and was able to get a new package of them! Great service!

I buy it because the tittle says 12 years of shelf life, obviously in Puerto Rico everybody buy batteries and storage because the huracane season, I hope was a good choice.

Looking to replenish the supply at home and ran across these at the club. Have not tried them yet, but the last batch of "copper tops" were made in China.

This is a great deal. The batteries are strong and last a long time. These are not "discount " batteries. They are quality batteries for a lower price.

Lasts as long as other, more expensive, name brands. We go through a lot of batteries for my husband's insulin pump. These last just a long as the Duracell batteries.

We use lots of AA batteries at our house, so we have bought lots of batteries. Members Mark batteries work just as well as other name brands while costing less.

These batteries have an outstanding shelf life. But of course our 9 year old Grandson has found our battery drawer, and now we don’t have to worry about that anymore!

Affordable and lasts for a long time even through having lots of battery operated toys and other things like candles. These last very long time and the price literally cannot be beat

Not much to say here because batteries are batteries. Only thing is the price is really good for the amount you get and they last as long as any others.

The order was placed and shipped quickly. I am a fan of Member's Mark products and have been buying the Member's Mark Batteries for years. They are excellent.
